may be readily applied to the exhaust-pipe.

oi any internal-combustion engine without necessitating any change in the construction of the parts and whereby th e exhaust instead .of mssing through thcnnulller may be quickly andetliciently directed to the atmosphere before reaching the mufller.

Referring to the drawing, Figure 1 is a view of my invention applied. to a simple form of automobile, a portion of the automobile being shown in section; Fig. 2 is an enlarged view showing the exhaust-pipe and my improved attachment in section, and the connections with the operating treadle; Fig. 3 is a longitudinal'section of a portion of the pipe with n'lyattaclnncnt applied thereto; Fig. 4 is a 01' ss-secti iin on the. line 4.4. Fig. 2; Fig. 5 is a plan-view of the operating treadle; and Fig. 6 is a section on the line Yr-6, Fi y I have illustrated my inv ntion as applied to an automobile of the Ford type, although its adaptation to other types oi? auton'iobilcs, and even tostationary ei1i ines will be apparent tin anyone, skilled in the art.

The numeral 2 designates the body porthe automobile, 3 the engine, and 4 \"l' aust-pipe leading to a suitable muf Ailvlv im 'iroved attachment consists of i 2 1 A a saiallwlikc valve body ha lugs 7 and the outlet 8. This outlet is normally closed by tl valve-flap 9 hinged at it) to the valve bod y. A lever-arn'i it is connected to the hinged member 10. A spring '22 is connected to the finger 13 on the l(\u1:1ll1'l ll and the opposite end of said spring is connected to the valve body at 14. This spring acts normally to hold the valve 9 on its seat 15.

To apply my improved attachmentto the exhaust-pipe 4, said exhaust-pipe is cut away at 16 and the saddle applied from below to inelose the opening 16. The yolies engage the upper portion of the cab; t

and bolts or other suitable fastening devices 18 connect said'yohes with the valve body through the lugs T. ln this manner. the attachment is quickly and readily secured to the exhaust-piiic and held-securely in position.

To provide for the operation of the valve 9 from a point within the automobile, the lever-arm 11 is connected by the cable 19 to the arm 20 connected to the treadle 521, said arm and trcadle being mounted on the pin journaled in the, bracket 92. A springoperated trip member ZS-is adapted to en gage the trcadle 21 when loreed down. as indicatedin Fig. 5. This trip member is quickly thrown out of engagement to release the trcadle. by the Foot of the operator, as clearly indicated in Fig. (1.

Vith the car running along under ordinary circumstances, the exhaust otthe engine will pass by the exhaust-pipe 4 through themuiller 5 in the ordinary manner, but when it is desired to cut out the mulller, the operator pressing his tool on the treadle 21,

moves the arm '20 to the position indicated in dotted lines. Fig. 3. whereupon the levcr- I arm 11 is moveihand through its connection with the valve 9. said valve is thrown upmulller, the exhaust being directed out through the outlet 8 directly to the atoms phcrc. \Vherc the cut-out is to be employed for any length oi time, the operator locks the treadle by the latch 23 and the exhaust continues to pass out througl'i the cut-out. \lhcn, however. it mulllcr into play again. the operator with his foot quickly releases the latch 2?, ind the sy'iriug arts to move the valve 9 to its clo't'ed position, as indicated in Fig. 2, where'- upon the exhaust then passes directly to the 'mnlllcr.

By my invention, I provide a simple form of cut-out, which consists of anattaehment which is very simple in construction and which may be made at low cost. which is very readily applied to'd'i'fierentstyles of automobiles. it only being necessary is desired to bring the o, one

cally no reconstruction of any kind, and the parts are so simple that it is not liable to get out of order.

What I claim is:

In a cut-out for internal combustion engines, the combination of im exhaust-pipe and muiiier, said exhaust-pipe having an elliptical-shaped opening formed therein intermediate the mother and the engine, a valve-body adapted to be secured to said pipe a valve-opening formed in said body in register with said first opening and having a valve-seat substantially flush with the exterior of said pipe, at flap-valve carried by said valve-body, said valve being so disposed 1 as to form a bottom wall substantially flush with the interior of said pipe above said valve-opening When in engagement with said seat, and adapted when raised to seat against the edges of the said first-mentioned opening .21

and the interior of the exhaust pipe to en- 'tirely close ofi communication to themufiler.
